Since 5/23/13 a pair of Baltimore Orioles have been regularly visiting my feeder. They seem to be interested only in eating the grape jelly. I have a nectar feeder and put out a piece of orange but they don't seem to be interested in them. I will only put out one small piece of orange from now on, hopefully they will decide to eat it . Last year I couldn't keep enough oranges out for them. At least they are coming to eat so I can enjoy their beautiful color.
